Hundreds of Hong Kong national security police raided the office of online pro-democracy media outlet Stand News on Wednesday and arrested six people, including senior staff, for suspected "seditious publications" offenses.
Stand News, set up in 2014 as a non-profit, is the most prominent remaining pro-democracy publication in Hong Kong after a national security probe earlier this year led to the closure of jailed tycoon Jimmy Lai's iconic Apple Daily tabloid.
The raid further raises concerns about media freedoms in the former British colony, which returned to Chinese rule in 1997 with the promise a wide range of individual rights would be protected.
